Figure 1
Displacement ellipsoid plot of (I) (with 40% probability ellipsoids), showing the dimeric unit with atom and ring labelling. Interactions within the dimeric unit are also shown, C—H⋯O as dashed lines, C—O⋯π(ring) as double-dashed lines. For symmetry codes see Tables 2 and 3; additional symmetry code: (i) 1 − x, 1 − y, 1 − z. |
